The average water heater is one of the hardest working appliances in the home. Traditional water heaters are on at all times, storing up hot water for when it’s needed. While this is certainly convenient, it also wastes quite a bit of energy throughout the year. Fortunately, there is an alternative for people who want to cut down on their home operating costs. Let’s take a look at tankless water heaters, and the advantages they provide.
How It Works
A tankless water heater, as the name suggests, doesn’t use a storage tank to hold and heat water. Instead, the system makes use of a heat exchanger similar to a boiler system. When there is demand for hot water, the tankless water heater turns on and heats water as it flows through the heat exchanger. Once demand subsides, the system turns itself off to save energy.
Pros and Cons
The pros of using a tankless water heater are pretty obvious. Compared to a tank water heater, a tankless system takes up less space and uses less energy throughout the year. These are the primary reasons that people choose tankless systems over other types. Tankless water heaters aren’t for everyone, though.
If you have a lot of people placing demand for hot water on the system, a tankless water heater will be more easily overwhelmed than its tank counterpart. For larger households, you may want to consider either installing a tank water heater or multiple tankless units. There is also a slight delay between when you first turn on the faucet and when you receive hot water, as the tankless system will be starting up from scratch every time. The delay is not long enough to be a significant problem. In addition, we strongly suggest having your water tested for hardness, since tankless water heaters perform best and last longer with soft water.
